Specification of Letters Patent No. 3,916, dated February 20, 1845.

To all 'whom t may concern: p

Be it known that I, JAMES W. NEWBERRY, of the Kensington district of theNorthern Liberties, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful improvement on the tool orinstrument called a shoemakers shoulder iron for setting and polishingthe edge or forepart of the soles of boots and shoes; and I herebydeclare the following to be a full and exact description.

The nature of my invention consits in so regulating by means of a screwand burs the extent of the surface designed for polishing, and the spacefor regulating the forepart or edge of the soles as to adapt it to sizeor thickness of any sole thus making one instrument answer for polishingand setting to a proper thickness-by well regulated guards-and sizedsole, in which respect 1t difers from thecontrivance now 1n use- Atowit-the present contrivance being the use of a separate instrument ortool for each sized sole, whereas my invent-ion makes one instrument ortool answer for any and every sized sole. i

To enable others skiled in the art to make and use my invention I willproceed to describe its construction and operation. The accompanyingdraft-plate No. 1, represents the instrument detached. The main arm B,is of iron (as is all the other parts of the instrument except thehandle which is of wood) about an inch long and about inch square, fromwhich project two parallel arms at right angles with B, marked 5, 6 and5, each about ofan inch in length and about that distance from eachother. On a line parallel with the under side of arm 6, at the oppositeside, B bevels upward until it comes to a peak about i of inch above thetop of arm on a line with the inside of B.

B and Z), b, are intended to support the instrument in general and slideA in particular, and bevels downward from the under side of arm Z9, b,until it joins the spiral stem which is inserted in the handle, thespace formed by B b and b b forms 3 sides of a hollow square into whichA, a square slide, intended to hold the screw D and suport guard a, t-swith exactness.

a is a projecting guard or arm about i of a inch in width, of the samethickness as slide A, to which it is connected by an elthe sole, andwith the peak at the top of .B, which is inserted in the seam betweenthe uper and the sole, regulates the thickness of the sole. Arm b is anhalf inch oval on the top, and of the same thickness as the spacebetween guard a and slide A into which space it ts with exactness whenthe instrument is brought together; and is designed to polish the edgeof the sole by pressing in against it and passing it there around.

In the angle formed by the peak at the top of B and arm b, is a small`head about the lg of an inch in size which is intended to compress theupper edge of the sole in the operation of polishing and setting it.

D is a screw about one inch in length and of an inch in diameter, firmlyembedded in the inner side of slide A about the center thereof, and isdesigned to pass through the main arm B at E, which is a screw holeanswering to the size of the screw, by means of which and the burs C, C,the instrument is connected, regulated and kept firm. a

C, C, are two burns about inch in di ameter and g of an inch thick whichare screwed on screen 1), the one inside and the other outside of arm B.By turning these burs the parts of the instrument are brought nearertogether or more widely separated, and thereby regulating the distancebetween the end of arm or guard a and the peak at the top of B which isthe space used for polishing the edge of the sole. By this means theinstrument is regulated so as to adapt it to the size of the thicknessof any sole, thus making one instrument to answer for setting andpolishing any size sole, while the burrs if one `be rmly secured againstthe inside and the other against the outside of arm B serves to keep thein strument rmly conected and the polishing and setting space true,after it is set and while in use. When thus set and regulatedV theinstrument is used as the common shoulmanner described, the distance ofthese tWo der iron is used. parts being regulated substantially in the Iclaim as my invention and desire to semanner set forth. cure by LettersPatent- JAS.
